The first of two 4 element SteppIRs (4Ls) was successfully installed
Saturday, 31 July, at the top of a 130 ft., guyed, Rohn 45G tower using a
PVRC Mount technique. The use of the PVRC Mount and a gin pole made it
possible for the SteppIR to be installed even with wind gusts of 15 mph and
a two element 40 meter beam mounted on the mast 15 feet above. (The second
4L will be mounted at the 100 ft level and fixed on Europe.)

In my situation, the PVRC Mount installation technique was possibly the
only way of getting the 4L to the top of the tower . Too many trees and my
house surround the base of the tower making it impossible to tram the
4L. A crane may have been able to get in, but it would have been if'y.

Using the PVRC Mount made getting the ant. in place relatively easy. The
heavy lifting was done by the ground crew.

A deviation was made to the PVRC Mount technique described in the ARRL
Antenna Handbook. The ant. was mounted to the mast using the antenna's
boom to mast plate. The Handbook's description of the PVRC Mount technique
has the ant. permanently attached to the Mount. The ground crew, using the
gin pole to lift the ant. off of the PVRC Mount's cross arm, allowed two of
us, Larry - K7SV, on top of the tower to easily maneuver the ant. into
place.

The above is provided as a possible technique someone else may use or
trigger a further modification of the technique for getting their ant. to
the top the tower.

install the 4L SteppIR are available via e-mail.
